REPAIRING AND NOT THROWING AWAY

Richtige Fernseher haben Röhren!

In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!
Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

UNIVERSAL ANDROID CHARGING PORT SETUP

This is a great replacement part if you can’t get hold of the original.

 









The standard Micro USB pinouts for power are below.








Next to Ground is the ID pin followed by Data+, Data- then VCC.
Some (very few) devices require the ID pin to be connected, this can be bypassed with a 130k resistor connected to Ground. This is supposed to be used to tell the device if an OTG cable is connected, hence rarely used for charging.

HOW TO UNLOCK_RESET - ANDROID MOBILE PHONES

HOW TO UNLOCK_RESET - ANDROID MOBILE PHONES

UNLOCK_RESET PROCEDURE
  On android phones you can activate a feature called pattern lock. This feature can be compared to a windows computer asking for password after the screen saver kicked in; only instead of a password you use a pattern. You get a screen with 9 dots and you draw a pattern of your choice with 4 of them. If you forget your pattern (or have kids that likes to play with phones) you will after 3 faulty attempts be unable to use the pattern to unlock it. Instead you are asked for your Google account and password (that is setup with the phone of course). This is where the problem starts. For many, many users providing the username and password won’t change a thing. for some people changing the password via a computer has worked but that is uncommon. Have no fear; there are solutions to almost everything.
Unlock android phones
1. Try entering null as password. (Together with your Google username)
2. Try entering your username without @gmail.com
3. Combine 1 and 2
4. Call yourself from another phone, answer, without hanging up press the home button, then menu button, settings, try to disable pattern-lock
5. Call yourself from another phone, answer, hang-up, directly after hanging up start pressing your buttons like a madman for <30-60 seconds ending with your home button (might take a while to get the timing right). go into settings and disable pattern-lock.
6.  Try the normal recovers password routine from gmail.com and start over from 1.
7. Perform a factory reset. you will lose all not-synced data (sd card will be left untouched).1-6 are possible workarounds, these doesn't work for everyone but can be worth a try to avoid factory reset.6.is what should work but hardly never does. 7-The factory reset always work.
End update
 In this case the solution is to make a factory reset (sometimes referred to as hard reset or wipe). This will erase all data on your phone (not on your sd-card). Your contacts and mails should be in sync with the Google servers, no problem there then. Downloaded applications needs to be installed again but there is a list of your previous downloads in the android market->my downloads. Other things though are lost if you haven’t backed them up manually with a 3-rd party application. Example on things you will lose: call logs, text messages, application settings.
This is the 3 step solution.  Factory reset your phone (links to android device manuals can be found below, it differs between devices)  Setup your phone just like you did the first time you unpacked it (use the same Google account if you want your old contacts back)  Restore any manual back-ups and install your previous applications from the my downloads list.  How do I factory reset? HTC leads the way and put this information in their manuals.

HOW TO DOWNLOAD AND INSTALL FOXIT AND ADOBE READER TO ANDROID MOBILE

How to DOWNLOAD AND INSTALL FOXIT AND ADOBE READER TO ANDROID MOBILE


PDF READER SOFTWARES

How to download and install Adobe Reader & Foxit Reader for Android [Samsung Galaxy Pro]
 To copy files from your computer, to the external SD card at your android smart phone
 The first step you should do is, to install Samsung “Kies” software to your desktop or laptop system.  You can get details about how to download and install the “Kies” software; by one among the post here.  Refer previous posts.  Without this software installed, the Galaxy won’t detected by your system.
The second step is to configure your phone with Wi-Fi to your modem.  I suggest so, because, it is the easiest and more dependable, than trying to download these 'ad ons' to your mobile, as I tried it by 2G mobile signals; the download was OK, but when the installation process started, it collapsed. 

 Now, you can start downloading the mobile versions of Foxit reader, and Adobe reader.  Try the following links to download the applications to your phone.  Do one by one, I suggest.  After successful download, the installation will start automatically, and will be noted with a ‘Successful’ indication by your phone.
 Foxit mobile PDF for android > Google play
 After successful configuration with Wi-Fi, turn on the Wi-Fi  to your phone, and turn off the Mobile data.  That is, by no way allow the mobile data to interfere with the Wi-Fi.  After successful download and installation, you can turn ON the Mobile Data back to ON, to get any updates for the installed application.  Prior to try to download these applications, it is a must that you should synchronize your Google account with your phone.  Just sign in to Google account, by entering the user name and password over phone.  It will be saved there, even after you switch off the phone.  The user name and password should be exactly same as you do sign in either with your desktop or laptop, because these reader applications downloads will automatically switch ON, by your main system.
 I’ll just describe the procedure to download the first stated here, as the procedure for the second is the same.  After doing all these, just connect the USB cable with your phone and system.  Check whether the system detects your phone by USB. If "Kies" software have been installed successfully, you can see the status of the connection at the task-bar.  If it is OK, proceed.  Turn On the modem Wi-Fi.  The phone will give you indication if it has been detected the modem and the Wi-Fi signal. 
 Click on the link; say to install the Foxit Reader.  Follow the instructions on screen.  You will be asked to sign in to your account.  Do it with same user name and password that you did with your phone. As soon as you pressed the install button on screen, ‘Installed’ will be shown.  This not an indication, that the application has already installed, but, the system has sent the download signal to the Foxit site, after successfully detected the phone, over your Google account. 
 From this point itself, the software will start to download to your phone, by Wi-Fi.  Do not disturb it.  It might take some time to download, and the time taken will depend on the data transfer speed to your internet connection.  Keep the system On, and the USB connected to the phone.
 After one application have been over, you can do the second.  The logo of the newly installed application will appear at the apps list to your phone as extra ones.
Now you can copy and paste the files in PDF, from your system to phone’s external SD card.

Understanding the Issue

Related errors
'Safe mode' displays on bottom of the Home screen
Cannot make calls or receive calls or access the internet
Some third-party apps do not start
  Safe mode only allows access to the device menus, without any connection to wireless networks and without starting some third-party apps. You need to exit Safe mode to make calls, send and receive messages, or connect to the internet.
  Safe mode can be used to stop a force close loop. A force close loop is when an app automatically force closes, then opens and closes continuously. Since you cannot access any of Android menus while in a force close loop, there is no way to close it. Placing a phone into Safe mode stops the loop and allows you to remove the app without a master reset.

  2. Wait at least 20 seconds so there is no charge left in the phone.
  3. Re-insert the SIM card and the battery.

  5. Press the Menu key a few times to verify it is not stuck.
  6. Turn on the device.Note: Do not press any keys while the phone is starting.
  7. If the device still starts in Safe Mode, then uninstall all apps that you recently downloaded.
  8. Restart the device. Note: If the device restarts, the issue was with one of the third-party apps. If you know which one it was, contact the developer or review the app to give feedback.
